This invention relates to improvements in car underitrames,-one object of the, invention being to provide asimple underira-ine 'to which .the body ofthe car 'inay'be a'ppli t without cutting away a considerable portion of the same.

' A i'nrtherobject is'to provideia substan 'tial steel end sill extending from side sillto sidesill for the body end-to-rest against.

A. further object is to provide-asimple end sill construction which will tornia bnffor for the car body. I

Withthese and other objects in View, the intention consists in certain no elfeatiires of construction and-combinationsot"partsas hereinafter set forth and point'ed out in the claims.

In the accompanying drawings; Figured, 18 a plan-view of a portion of acarunderframe, showing an embodiment of-my inventicn; Fig. 2 1s a lcngitudinal'se'ction ot t-he sa .e on the lineZ-Z ofFig.- 1 3 i's'anenlarged partiahplan View of" the sill structure :and its connecticnwitli' a side sill Fig; l

shown in Fig, 3;. Fig. 5 is a plan-view of a portion of'tlie'endsill channel; Fig, 6 is a transverse sectional view thronglitliecentral portion of the end sillstructure; showingthe position occupied bythe-body end sill; Fig. '7 is adetail iew of one of the guss'ets torc'onn'ecting theend sill with the side sills; Fig. 8 is a transverse sectional View through the end sill at one of the end pests; and Fig. 9 is a fragmentary plan View, partly in section, of the structure shown in Fig. 8.

1, 1, represents the center girder members of a car underframe, and 2, 2, the side sills. The depth of the center girder is reduced gradually from the center of the underframe to points rearwardly of the car bolsters, and those portions 3 of said center girder which are disposed over the trucks of the car (not is a front elevation" of the structure? shown) are of" shailow' approximately runi form depth. The reduced portions 810i the center" girder, are connected withthe side sillsb'y loolster'memberse, at. A cover plate e is secured over and connects the upper flanges of center girderxmembers' and extends approximately'i'rcm end toend of.

At each end of the-nnderfranm; the forward ends of the center girder members are recessed as shown at"6,' for the accommoda= tionof my improved. end sill structure,-

(hereina'tt'er described in detail) and these:

recessed end porticnsof the center girder members may be formed, by means ot cen ter girder extensions Tsecured to the main center girder members somewhat below/the ilane' of g the tops =01 the "l atter' and proj ecting iiorwardly beyond the same: In View of this dropping of the forward ends the center girder members; the bottonr angle beams of the latter will bedi'opped some what, as shown at 8.

My improved end sill comprises steel end sill channel 9 which extends across the depressed center girder extension, and is-diss nosed with its' flanges-proiecting rearwardly The respective endsof the end sill channelarecnrved rearwardly, asshown at 10; 31 and and terminate-near the forward endsof' the side sills; The end sill structure also compri'ses a sheet metal member 11 secured at its-outer edge to the upper flange of the end sill channel 9; fronr which it extends rearwardly as shown at 12' then downwardlyas shownat' l g and thenrear wardly as shown at 14, the portionll being seated at its center err-thedepressed center girder extension. In this manner a boxshaped end sill structure, open at its bottom, is formed and extends from side sill to side sill of the underframe. Y

The steel box or hollow end sill structure is connected at its ends to'the ends of the side sills hv means of gussets 15, such as shown in Fig. 7. Each of these guests is secured to the end portion of a side sill. and has portions which extend under the lower horizontal portion 14: of the end sill sheet 11 and under the end sill channel 9, to both the side sills and the center a of which it is securely riveted. That portion of the end sill structure over the rear horizontal member 14 of the end sill sheet and the vertical member 13 thereof, forms a pocket in which the wooden end sill 16 of the car body is seated. Thus my improved end sill structure affords an end seat for the car body,. from side sill to side sill, and permitsthe body to be readily placed in pcsition,no other tie than the bolts which hold it tothe underframe being necessary. It will be observed also that my improved steel end sill constitutes an abutment for the body end sill, and that both are in the same plane. V i V p The top horizontal portion 12 of the end sillstructure is slotted ,as shown at 17 for the accommodation of end post or stil'feners 18 for the end of the car body, and the upper flange of the end sill channel 9 is notched, as at 19, for the same purpose. Each post 18 extends downwardly into the box end sill structure and its lower end is secured between anchoring angles "20 secured to a plate 21, the latter extending transversely under the end sill structure and riveted to the lower flange of the channel 9 thereof and to the rear memberl l of the sheet 11. Similar anchoring angles 22 are secured upon the top member 12 of the end sill structure posts. 7 v I i Various slight changes might be inadein the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to vrestrict myself tothe precise details herein set forth.

Having fully describedmy invention what I claim as new and desire to secure by Let-' ters Patent, is n 1. The combination with the side sills of a car underframe, of an-end sill structure comprising a; member disposed forwardly of the ends of the side sills and projecting above the ing rearwardly extending end portions secured to the side sills, and a plate member comprising an upper horizontal portion se cured to the upper edge of the first mentioned end sill member, a lower horizontal secured to the top of the end sill and to respective sides of the end extending from oneside sill to the other.

horizontal plane thereof and havportion connected with the side sills and a vertical portion connecting said upper and lower horizontal portions. j I

2. The combination with the side sills of a car underframe, of an end sill structure comprising an. end sill channel proiecting its ends connected with the latter, a plate memberhaving an upper horizontal part channel, a lower horizontal part disposed between the side sills and secured thereto, and a vertical part connecting said upper and lower horizontal parts, and plates secured to the bottom of, the end sill channel and to the beyond the ends of the side sills and having lower horizontal part of the plate member of the end sill structure. v

3. The combination withthe side sills and center girder. ofa car underframe, of an end sill channel 'havingrearwardly turned end portions, a. plate secured at its outer edge to the upper edge of saidend sill channel and comprising a horizontal member, a vertical member and a lower horizontal member, the latter mounted on "the center girder and extending fromone side sill to the otheiy fand means securing the ends of said plate and theends of the end sill channel tothe side sills;

4. The combination with the side sills or a car underframe, of an end sill structure said end sill structure comprising an end sill channel, and a plate comprising a top horizontal member secured to the top of the end sill channel, a vertical member and a bot tom horizontal member, said top member having slots to receive end posts, anchor angles securedjupon the top member of said plate, transverse plates secured under the end sill channel and the lower horizontal 'member of said plate,pand pcst anchors secured to said transverse plates and located within the end sill structure.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
